Arctic summer sea ice could disappear by 2030s, study finds.
TL;DR Summary
The Arctic could be free of sea ice during September as early as the 2030s, a decade earlier than previously projected, according to a new study. Even if the world makes significant cuts to planet-heating pollution today, the Arctic could still see summers free of sea ice by the 2050s. The study found that declining sea ice was largely the result of human-caused, planet-heating pollution, and previous models had underestimated Arctic sea ice melting trends. An Arctic with no summer sea ice would send dire ripple effects around the world, including extreme weather events and increased commercial shipping.
